sEeIFiAr-'roforming part of Letter-s' Patent No. 630,533, dated August s, 1899.

Applieatinn filed April 8, 1398. Serial No.` 676,861. (No model.)

To a/ZZ whom it may 'con/cern: V

Be it known that I, JOHN M. FISKE, of East Orange, in the county of Essex and Statev of New Jersey, have invented certain new and useful Improvements in Stall-D rains,of whi ch the following is a full, clear, and exact descrip# tion. f

My invention relates to improvements in stall drains and iioors such as are used in horse and cattle stalls; and the objects of myv invention are to produce a comparatively cheap and simple apparatus adapted to form a part of the bed or oor of a horse or cattle stall; to produce a device adapted to aord perfect drainage, whereby the surface of the stall-iioor is kept dry and clean; to produce a device which holds the slats of the door in such a manner that they cannot lie at any point in liquid and so rot or become foul; to produce means whereby the slats can be instantly and easily removed and used either side up or either end forward, to the end that the slats may be made to last until worn out to construct a drain having its bed or box arranged so that a hook or fork can be readily drawn through it'for cleaning purposes; to produce a bed or box having a iii-m, cheap,

and convenient means for supporting the slats; to construct a device of this character adapted to make a very close and permanent connection with the adjacentfloor; to pro'y vide means for removing or getting at any 'part of the drain, and in general to produce an article of this character adapted to`form a perfect iioor or bed which is thoroughly and efliciently drained. l

To these ends my invention consists of cer`^ tain features of construction and combination of parts, which will be hereinafter fully described and claimed.

Reference is to be hadto the accompanying drawings, forming a part of this specication, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a planview of myimproved apparatus with the slats removed. Fig. 2 is a longitudinal section, on the lines II II of Figs. 1 and 3, with the slats in position. Fig. 3 is a cross-section, on the line'IlI III of Fig. 1, with the slats in position for use; and Fig. 4

is a perspective view of the device with a por# tionof the slats removed.

The drain has a box or bed 10, Whichis not broadly new, but which has an inclined bottom, thel inclination extending from the four sides to a point adjacent to the center, where all liquid is trapped off, as particularly described hereinafter, and the box has an upturned i'langell near the edge and an outwardly-projecting base-flange 12, which is thickestat its outer edge, as shown clearly in- Figs. 2 and 3, thus giving it an inWardly-in clined top surface adapted to form a very close connection with the permanent floor 13, which is laid so as to overlap this baseflange, and the joint should be iilled with lead or similar material, so as to form aclose seal. A similar seal is made where the permanent door overlaps the top of the flange 11, as shown in Fig. 2, and it will be noticed that a tight seal is effected and that the inclination of the iange 12, together with the corresponding groove of the floor 13, which receives'the iiange,causes the latter to be always held close against the flange 13, so that the seal just described is permanent, and there is no chance for moisture of any kind to get between the floor and box 10 to the detriment of the iioor and consequent uncleanness of l the stall'.

Thebox 10 has an opening at its lowest point through which the liquor or water passes, 'and this opening is closed,- usually, by a perforated cover 14, whichfor vconvenience yI have shown provided'withv knobs 15, by Awhich itmay be removed. Below the opening referred to is a trap 16, which may be of any usual form so far as its interior is concerned and which therefore I do not describe k in detail. The trap has the usual bell 17, which is secured, for convenience, to the cover 111, and it delivers into the T branch 18 of the drain-pipe 19, through which the drainage from the stall is carried o, as usual. The only novel feature in connection with the trap and drain-pipe is the means of suspending the latter, which I do by the stirrup or hanger 20, the said stirrup or hanger having its ends arranged to engage the hook or lug 21 on the outside of the trap 16. The trap is bolted to IOO the box 10, and thus the drain-pipe is supported securely when hung as described, and it can be readily removed by simply removing one of the ends of the stirrup from its supporting-hook 2l.

On the upper surface of the box l0 and at proper intervals, preferably points near the center, are lugs or supports 22, which extend vertically upward and are adapted to support the slats 23, which are spaced apart, as usual, to provide for the downllow of liquor between them. These lugs or supports 22 are arranged so that there shall be a space between adjacent supports, the spaces registering with the spaces between the slats 23, and the front of each support 22-that is, the part facing the nearest end of the box lO-is inclined from the center toward each edge, thus making the lug or support to form little obstruction to the flow of liquor toward the drainageopening of the box, and this construction of the supports also enables a cleaning-hook to be drawn between the slats 23, so as to remove any straw, manure, or other obstruction which may fall between the slats. It will be seen that if the cleaning-hook strikes a support 22 the shape of the support dellects the hook, lso that it passes readily between adjacent supports. Y

At the rear end of the box 10 and next the flange ll is a raised platform or ledge 24, which forms a support or rest for the rear ends of the slats 23, the said platform or ledge extending entirely across the box, so as to form a common support for all the slats. This keeps the ends of the slats above the normal surface of the box lO and keeps the said ends dry. Extending upward from the ledge 24 are lugs 25, the spaces between which form sockets to receive the slats 23, and these sockets hold the slats securely, so that they cannot rock or be laterally displaced. The slats at their forward ends are similarly held and A also guided to place by lugs 26, which project inward and rearward from the top of the inturned flange 27, which flange is adapted to engage the transverse groove 2S in the ends of each Slat 23. The inner ends of the lugs 26 are rounded, as shown in Fig. l, so that when the slats are pushed forward to place they will be guided by the lugs and centered between the said lugs. At the front end of the box l0 and beneath the inturned flange 27 is a rounded and raised rib 29, which has a slight inclination'toward the general plane of the box l0, and thus it will be seen that the slats 23 may almost be thrown to place, because when pushed forward the rib 29 raises them up to cause the groove 28 to register with the flange 27, while the rounded lugs 2G, striking the side edges of the slats, center them, and so the slats are very easily placed. lVhen once in position, the rear ends drop between the lugs 25 and the forward ends take the position as just described, and the said forward ends are raised to a dry position by the rib 29. In this position (see Fig. 2)

tion is made and there is no danger of splitting the slats. The slats are likewise held on the supports 22 and form an extremely solid lloor. The slats have the transverse groove 28 in each end, an'd so it will be seen that when the slats become worn they can be turned over, as the grooves 2S are central, and it will be further seen that if they are worn near one end more than the other they can be turned end for end.

From the foregoing description it will be seen that the main portion of the apparatus can be cast in a single piece, that the slats are held so as to be easily removed and so as not to be accidentally displaced, that they can be used until entirely worn out, and that the arrangement described forms a cheap and efficient drain.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A device of the kind described, comprising a box having an inclined floor with a drainage-opening at the lowest part thereof, spacing-lugs at the rear end of the box, a raised and inclined rib at the front end of the box, and an inturned flange at the front end of the box, said flange projecting essentially parallel with the aforesaid rib, substantially as described.

2. The combination with a box orbed having an inclined floor, of the independent slatsupports projecting upward from the floor, said supports having theirV front faces inclined, substantially as described.

3. The combination with the inclined box having rear-end Slat-supports, of the inclined raised rib at the front end of the box, the i11- turned flange above the rib, and the rearward-projecting lugs on the said flange, substantially as described.

4f. rlhe combination with the box having at its forward end the inclined raised rib, and the inturned flange above the rib, of the slats having transverse end grooves fitting over the flange, substantially as described.

5.
